Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.
Switching on/off
To start the power tool, push the on/off switch (3) forward.
To lock the on/off switch (3) in position, push the on/off
switch (3) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (3);
or, if the switch is locked, briefly push the on/off switch (3)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
Speed preselection

You can preselect the required speed using the speed
preselection thumbwheel (4), even during operation. The in-

move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Restart protection
(GWS 9-115 / GWS 9-125 / GWS 11-125 /
GWS 12-125 CI / GWS 12-125 CIE / GWS 15-125 CI /
GWS 15-125 CIE / GWS 15-125 CIT / GWS 15-150 CI /
GWS 15-125 Inox)
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (3) to the "off" posi-
tion and then switch the power tool on again.
Starting current limitation
(GWS 12-125 CI / GWS 12-125 CIE / GWS 15-125 CI /
GWS 15-125 CIE / GWS 15-125 CIT / GWS 15-150 CI /
GWS 15-125 Inox)
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the starting current limit-
ation and restarting protection mechanisms have failed. The
power tool must be sent to the after-sales service immedi-
ately; see the "After-Sales Service and Application Service"
section for addresses.
Kickback stop
(GWS 12-125 CI / GWS 12-125 CIE / GWS 15-125 CI /
GWS 15-125 CIE / GWS 15-125 CIT / GWS 15-150 CI /
GWS 15-125 Inox)
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
To restart the tool, set the On/Off switch (3) to the "off" po-
sition and then switch the power tool on again.
Constant Electronic control
(GWS 12-125 CI / GWS 12-125 CIE / GWS 15-125 CI /
GWS 15-125 CIE / GWS 15-125 CIT / GWS 15-150 CI /
GWS 15-125 Inox)
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
